铝合金挤压模具报废后再利用的研究

Research on reuse of aluminum alloy extrusion die after scrap

阐述了一种"废改模具+内嵌块"工艺,该方法可以达到报废模具再利用目的。通过对报废模具选取、退火处理、机加工、淬火+回火处理等一套流程操作来实现废模的改造。内嵌块为体量小、加工方便、拥有工作带的模具的一部分,改造后的模具与内嵌块相配合便形成一套完整的模具。经现场生产的使用情况表明:废改模具+内嵌块的模式具有降低生产成本、更换迅速、蚀洗方便等优点。

This paper introduces a method of reusing scrap die by using scrap die+embedded block,and the reform of scrap die is real⁃ized through the operation flow of selecting scrap die,annealing treatment,machining treatment,quenching+tempering treatment.The embedded block is a part of the die with small volume,convenient processing and working belt.The modified die and the embed⁃ded block cooperate to form a complete set of die.The application of on-site production shows that the mode of scrap die+embed⁃ded block has the advantages of reducing production cost,rapid replacement and alkaline cleaning convenient.
